(end_input_void_port): renamed to end_input_default.
* init.c (scm_standard_stream_to_port): create a void port instead
of opening /dev/null if the standard file descriptors are bad.
advantages: no portability problems, doesn't waste a file descriptor,
simplifies the code (thanks to Marius for the idea).
* vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
* void ports: make reading from a void port give EOF instead of
segv:
* ports.c (s_scm_sys_make_void_port): modified docstring.
(fill_input_void_port): new proc.
(scm_init_ports): set up fill_input_void_port.
* ports.c (scm_port_non_buffer): new proc.
(scm_void_port): call scm_port_non_buffer.
* fports.c (scm_setvbuf): docstring: remove the fcntl documentation
which was incorrectly appended.
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
that caused a seg fault. Also fixed `set-port-column!'s
docstring. Thanks Han-Wen Nienhuys for finding the bug!
regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
strings.c, variable.c: Added lots of documentation, cleaned up
some existing documentation. Occasionally changed formal params
to match docs. Also folded an #ifdef into the inners of a
primitive instead of having two copies of the primitive
(`get-internal-real-time', from stime.c)
* error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
* strings.c (scm_string_ref): make the 2nd argument compulsory.
previously it defaulted to zero for no good reason that I can see.
use a local variable for SCM_INUM (k). replace
SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
(scm_makfromstr): cosmetic changes.
(scm_string): Accept only chars in the list, not strings, for
conformance to R5RS (particularly for list->string, which is
supposed to be the inverse of string->list.) remove
SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
scm_makstr handles the cell allocation. when reporting wrong-type
arg, don't report the position as 1.
* posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
* boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
to string-append.
SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
variants.
* ports.c (scm_port_closed_p): Validate that the arg is a PORT,
then return whether it's an open port (was validating that it was
an open port -- this was a bug I introduced back in December, but
my careful reading of diffs caught it).
* numbers.c: Recombine the two conditional-compilation paths for
all the log* primitives -- they were split based on #ifndef
scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
some bugs and inconsistencies in the two sets of implementations.
(scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
* ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
SCM_VALIDATE_INUM_COPY once where it should've been used.
* fluids.c (scm_internal_with_fluids): Use
SCM_VALIDATE_LIST_COPYLEN.
* filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
this is questionable as it relaxes type safety, but other changes
were useful and all SCM_NUM2LONG's should probably be
revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
* evalext.c: line-break change on 1 line.
* eval.c (nconc2last): Takes a non-empty list as its first
argument, not just a list.
* dynl.c: Use new SCM_COERCE_ROSTRING macro.
strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
consistency with the other macros dealing with immediate
characters. (Similar to INT -> INUM change a week or so ago).
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.
* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this
in terms of SCM_SLOPPY_NCONSP instead of repeating the
expression.
* symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
define latter in terms of sloppy variant.
* strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
define latter in terms of sloppy variant.
* scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
out the commonality of the various basic SCM_VALIDATE_foop
macros. Use SCM_MAKE_VALIDATE macro where possible. Fix
SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
coercion to an integer which is more advanced than desired and
SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE
appropriately for the various _MIN, _MAX, _RANGE macros. Drop
some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
part of its SCM_CONSP test).
* socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS.
SCM_NIMP test integrated into an || clause that I'd missed before
and was causing a segfault in the regression tests.
* symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not
(char *); fixes a problem reported by the regression test
ports.test.
* ports.c: Fixed a couple of arg/number mismatches in
SCM_VALIDATE_ macros.
Now passes the (not-comprehensive) guile-modules test-suite again!
* scm_validate.h: Added SCM_VALIDATE_THREAD.
* *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
that SCM_FOOP macros all now include SCM_NIMP in their expansion.
This simplifies lots of code, making it far more readable.
* guile-doc-snarf.awk.in: Added.
* ports.c (s_scm_pt_member): Fixed validation.
* guile-doc-snarf.in (filename): Use basename in order to strip
away path.
* debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
semicolon.
(scm_memcons, scm_memcons, mem_to_proc): Renamed function name
strings to new form.
* backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
* tags.h (SCM_UNBOUND): New iflag which is needed for some time to
mark the unboundness of a GOOPS slot. (Added now in order to
correct a oversight. Should probably be removed again and
replaced with SCM_UNDEFINED when the corresponding code in GOOPS
is rewritten.)
* print.c (scm_isymnames): Added printed representation for
SCM_UNBOUND.
* eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
SCM_IM_SLOT_REF.
GUILE_PROC1. Build guile-procedures.txt, and add that file to
pkgdata_DATA.
* load.c: Added `pkgdata-dir', `site-dir', `library-dir'
primitives.
* guile-doc-snarf.awk: Drop trailing space when no arguments:
e.g., "(foo )" is now "(foo)".
* *.c: moved all the documentation for primitives from
guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
This leaves about half of the primitives undocumented. Also, all
the markup is currently still texinfo. I don't have a problem
with texinfo per se, but the markup is not very descriptive or
accurate.
function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
caller of the ptob seek procedure to the implementation. This
gives more control in general to the ptob seek: in particular the
change of 1999-10-20 can be made to work without breaking seek on
string ports. There's a comment in NEWS about upgrading port
types.
* ports.c (scm_seek): don't reset the port buffers here.
* fports.c (fport_seek): reset the buffers, except for the
0 SEEK_CUR case.
* strports.c (st_end_input): (bug fix): decrement pt->read_pos by
offset. check that it's not less than read_buf.
(st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
case and currently reading.
random access. rw_active needs to be maintained even for single
directional ports, otherwise scm_seek and probably other things are
broken. (thanks to Roland Orre).
* strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
* ports.c (scm_add_to_port_table): initialise rw_random to 0.
* ports.h (scm_port): change the comments on rw_random and rw_active.
not a correct substitute for memmove, because it doesn't handle
overlapping source and destination areas on many platforms.
Overlaps are the primary reason to use memmove in the first place.
* ports.c (scm_ungetc): Same.
* strop.c (scm_substring_move_x): Same.
testing (otherwise the port-print-state trick won't be transparent
to the user; one example where this caused problems was in the
(ice-9 format) module).
SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
zero). The debugger knows about enums, but doesn't know about
#defines.
(typedef scm_port): Declare rw_active member to be an enum
scm_port_rw_active.
* fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
instead of zero.
* ports.c (scm_add_to_port_table): Same.
* strports.c (st_flush, st_end_input): Same.
* ports.c (scm_seek): one more: was scm_lseek. Also changed the
Scheme name from lseek to seek, but lseek was added recently so
it shouldn't be a big problem.
* ports.c, gdbint.c, ioext.c: changed callers.
* fports.c (fport_input_waiting): if select is used, return 1
instead of whatever FD_ISSET expands to. maybe it will be useful
to interpret the value from the input_waiting ptob procedure as a
lower bound on the number of bytes available.
* Mikael asked for a few names to be changed...
* ports.c (scm_make_port_type): take the write procedure as the
second argument instead of the flush procedure.
* ports.h (scm_ptob_descriptor): rename the ptob procedures:
fflush -> flush, read_flush -> end_input, fclose -> close,
fill_buffer -> fill_input, ftruncate -> truncate,
input_waiting_p -> input_waiting.
* ports.c (end_input_void_port): was read_flush_void_port.

(scm_set_port_flush): was scm_set_port_write.
(scm_set_port_input_waiting): was scm_set_port_input_waiting_p
(scm_end_input): was scm_read_flush.
(scm_fill_input): was scm_fill_buffer.
(scm_flush): was scm_fflush.
* fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
(fport_end_input): was local_read_flush.
(fport_flush): was local_fflush.
(fport_close): was local_fclose.
(fport_truncate): was local_ftruncate.
(fport_seek): was local_seek.
(fport_free): was local_free.
(fport_fill_input): was fport_fill_buffer.
* strports.c (st_end_input): was st_read_flush.
(st_truncate): was st_ftruncate.
* vports.c: (sf_flush): was sfflush.
(sf_close): was sfclose.
(sf_fill_input): was sf_fill_buffer.
* ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
change callers.
* ports.c (scm_putc, scm_puts),
* unif.c (scm_uniform_array_write): use scm_lfwrite.
* ports.c (scm_putc): change type of first argument from int to char.
it's more efficient for unbuffered fports (e.g., sockets.)
* ports.c (scm_puts): use ptob->write.
* vports.c (scm_make_sfptob): set write proc in ptob.
* strports.c (scm_make_stptob): set write proc in ptob.
* ports.c (write_void_port): new procedure.
* vports.c (sf_write): new procedure.
* ports.c (scm_lfwrite): use ptob->write.
* strports.c (st_write): new procedure.
* fports.c (fport_write): new procedure.
(scm_make_fptob): set write in ptob to fport_write.
* ports.h: prototype for scm_set_port_write.
* ports.c (scm_make_port_type): initialise ptob write procedure.
(scm_set_port_write): new proc.
creation of port types (replaces scm_newptob). Just as for the
smobs, we need to separate the internal representation of smob
types from the interface, so that we easily can add new fields and
rearrange things without caring about backward compatibility.
This change was forced by the need in GOOPS to create classes
representing port types.
(scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
scm_set_ptob_seek, scm_set_ptob_truncate,
scm_set_ptob_input_waiting_p): New setters.
(scm_newptob): Rewritten to use scm_make_port_type. For backward
compatibility.
(scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
(scm_prinport): Removed.
(scm_port_print): Added.
(scm_print_port_mode): Added.
(void_port_ptob, print_void_port, close_void_port, noop0):
Removed. Removed #include "genio.h" Added #include "objects.h",
#include "smobs.h"
* gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
* ports.c (scm_truncate_file): renamed from scm_ftruncate.
allow the 1st argument to be a fdes or filename as well as a
port (as in the filesys.c version).
* filesys.c (scm_truncate_file): removed.
